Specific embodiment
The specific embodiment of embodiment of the present invention is described in detail below in conjunction with attached drawing.It should be understood that
The specific embodiments described herein are merely to illustrate and explain the present invention embodiment, are not intended to restrict the invention implementation
Mode.
Fig. 1 is postponed according to the projection for reducing mobile device screen to vehicle device screen that embodiment of the present invention provides
Method flow chart.As shown in Figure 1, it in embodiments of the present invention, provides one kind and is arrived for reducing mobile device screen
The method of the projection delay of vehicle device screen, this method can include：
Crawl processing is carried out to the content of mobile device screen to generate the first data；
Conversion process is carried out to the first data to obtain the second data；And
Coded treatment is carried out to the second data to obtain third data；
Wherein, at least the two in crawl processing, conversion process and coded treatment can carry out parallel.
Mobile equipment may, for example, be mobile phone, tablet computer, personal digital assistant (PDA) etc..Mobile phone may, for example, be base
In the mobile phone of Android system.By taking the mobile phone of Android system as an example, when mobile phone is for example interconnected by USB line and vehicle device, to complete
Mobile phone screen picture is projected into vehicle device screen (referred to as throwing screen), mobile phone completion is needed to grab screen, conversion and encoding operation.In order to
It is enough efficiently to complete these operations, queue and thread can be quoted.In embodiments of the present invention, this method can be with
Including：First data are input to first queue；Wherein conversion process includes taking out the first data and right from the first queue
First data carry out conversion process.In this embodiment, for example, mobile phone will to grab the obtained data (the first data) of screen operation defeated
Enter to first queue.Furthermore it is possible to conversion process is performed in first thread.The first thread takes out the first number from first queue
Conversion process is carried out according to it.If first queue has expired, can be discharged with waiting list again to the first number of first queue input
According to.Coded treatment can also use queue and thread.For example, can be input by the second data that conversion process obtains
Two queues.Coded treatment can carry out in the second thread, which can take out the second data and right from second queue
It carries out coded treatment.If second queue has expired, it can wait for second queue release again to the second number of second queue input
According to.In this embodiment, at least two processing during shielding are thrown by the way of queue, therefore can be carried out parallel, with
It serially carries out processing to compare, execution efficiency is improved.
In embodiments of the present invention, conversion process can be included at scaling processing, format conversion processing and/or rotation
Reason.It will be understood by those skilled in the art that conversion process can include the arbitrary combination of these three processing according to actual demand.
Fig. 2 is the projection for reducing mobile device screen to vehicle device screen provided according to another embodiment of the present invention
The flow chart of the method for delay.As shown in Fig. 2, in embodiments of the present invention, this method can include：
Crawl processing is carried out to the content of mobile device screen to generate the first data；
First data are zoomed in and out with processing to obtain scaling treated data；
Format conversion processing is carried out to scaling treated data to obtain the data after format conversion processing；
To form, transformed data carry out rotation processing to obtain the data after rotation processing as the second data；And
Coded treatment is carried out to the second data to obtain third data.
Wherein, in crawl processing, scaling processing, format conversion processing, rotation processing and coded treatment both at least simultaneously
Row carries out.
By taking the mobile phone of Android system as an example, when mobile phone is for example interconnected by USB line and vehicle device, to complete mobile phone screen
Picture projects vehicle device screen (referred to as throwing screen), and mobile phone completion is needed to grab screen, scaling, format conversion, rotation and encoding operation.For
It can efficiently complete these operations, queue and thread can be quoted.In this embodiment, for example, mobile phone will grab
The data (the first data) that screen operation obtains are input to first queue.Furthermore it is possible to scaling processing is performed in first thread.It should
First thread takes out the first data from first queue and processing is zoomed in and out to it.If first queue has expired, team can be waited for
Row release inputs the first data to first queue again.
Format conversion processing can also use queue and thread.For example, treated for the scaling handled by scaling
Data are input to second queue.Format conversion processing can carry out in the second thread, which can be from second queue
It takes out scaling treated data and format conversion processing is carried out to it.If second queue has expired, the second team can be waited for
Row release is again to second queue input scaling treated data.
Rotation processing can also use queue and thread.For example, the format conversion processing obtained by format conversion processing
Data afterwards are input to third queue.Rotation processing can carry out in third thread, which can be from third queue
It takes out the data after format conversion processing and rotation processing is carried out to it to obtain the second data.If third queue has been expired,
The third queue release data after third queue input format conversion process again can be waited for.Those skilled in the art can manage
Solution, in some applications, it may not be necessary to rotation processing.
Coded treatment can also use queue and thread.It for example, can be defeated by the second data that conversion process obtains
Enter to the 4th queue.Coded treatment can carry out in the 4th thread, and the 4th thread can take out the second number from the 4th queue
Coded treatment is carried out according to and to it.If the 4th queue has been expired, the 4th queue release can be waited for be inputted again to the 4th queue
Second data.In this embodiment, at least two processing during shielding are thrown by the way of queue, therefore can and be advanced
Row, compared with serially carrying out processing, execution efficiency is improved.
Although describing scaling processing, format conversion processing and rotation processing in a particular order in the above-described embodiment,
But it will be appreciated by those skilled in the art that according to practical application, these processing can be other sequences, can only need this
In a little processing some or other processing can be added.
